Trivia

Chespin seems to resemble a tree - the head is compared as leaves and the body theFile:Cn.png lower part of the tree.

Chespin is the first Grass-type starter Pokémon that is not reptile-based but based on a mammal, in this case a rodent or a marsupial. Judging by its Japanese, English, French, German, Spanish, Italian and Korean name, it appears to be based on a hedgehog.

Chespin will be the third grass starter to stand on two legs, with the first being Treecko and the second being Snivy.
